Question

What is isotropic field and ligand field in coordination chemistry?

Answer 1

Answer:

Isotropy is uniformity in all orientations; it is derived from the Greek isos (ἴσος, "equal") and tropos (τρόπος, "way"). ... Isotropic radiation has the same intensity regardless of the direction of measurement, and an isotropic field exerts the same action regardless of how the test particle is oriented.

Explanation:

"t" refers to triply degenerate levels orbitals. It consists of three d-orbitals. ... The "g" tells you that the orbitals are gerade (german for even) - they have the same symmetry with respect to the inversion centre. And "eg" means "Exempli Gratia" in Latin- which translates to English as "By way of example".

Ligand field theory, in chemistry, one of several theories that describe the electronic structure of coordination or complex compounds, notably transition metal complexes, which consist of a central metal atom surrounded by a group of electron-rich atoms or molecules called ligands.
